Ill be waiting for HKJs review, just like I did with each version so far. Im yet to buy one of their chargers, theyre close, but never quite there for me. I dont care about saving $10 so was not motivated by group buy deadline pressures.

The comment on Amazon is from a random user and should not be taken as gospel. I wouldn’t be surprised if the C3400 is the same as the C3100 V2.1.

No, it’s from the seller, and called out as such.

I suspect that you are right though about it being the same as the C3100 v2.1. Someone realized that giving it a new name and label is a lot better way to clearly communicate that it is the new and improved version, and avoid people passing off old stock as new.

Or it could be as simple as they wanted to first use up all the cases that they had made up that said BT-C3100. I don’t think they expected to update the unit so soon after the release of v2.0

HKJ suggested that maybe there is an included hardware upgrade. From the Amazon site this C3400 has been in their hands since September. Is it possible OPUS could have made a hardware change that quickly after the release of v2.1?

Just emailed Robert ( rdana from ebay)
This is what he said…..
The BT-C3400 is essentially the C3100 V2.1. This model number is exclusive to me.
Thanks,

I’m gonna buy one from him since it is the new 2.1 version.

So, there is no group buy for BTC-3400 this time :bigsmile:
Good. My BTC-3100 is still in waiting for final delivery from the post office. Maybe I’ll receive it in 1-2 days.
I’d better kill myself if there is already another groupbuy for a newer version even before I receive my BTC-3100 2.1 |(

Thanks, now I’ll be able to read up before my BT-C3400 arrives (by Saturday).

Ended up ordering the BT-3100 with the European ac/dc power adapter (KYT120300BV), come with a Euro/US add-on adapter, which I guess I lost.
Where in the USA can I order a replacement AC/DC power unit, for my BT-3100?
(I would rather just get the whole power unit, and not have to use the euro/US adapter)
